Cytosorbents Corporation is a critical care company specializing in blood purification technology to treat life-threatening conditions. Its proprietary platform is based on biocompatible, highly porous polymer beads that use hemoadsorption to remove harmful substances, such as inflammatory mediators and certain drugs, from blood. The company's flagship product, CytoSorb, is an extracorporeal blood purification therapy used in intensive care units and during cardiac surgery to help restore physiological balance. The technology is also applied in other products for ex vivo organ perfusion (ECOS-300CY) and veterinary critical care (VetResQ).
